The ASX200 - a market capitalisation-weighted price index - currently stands at 6100 , following an increase of 21% over the previous 12 months. The dividend yield on this market was 3.5% during the same time period. The standard deviation of total returns on the market was 18%. A corporate bond index generated a total return of 6% during the 12-month period, with a standard deviation of returns of 10%. The covariance of returns between the ASX 200 and the corporate bond index was 0.01. Assume you choose a benchmark portfolio - a typical superannuation portfolio which holds 70% of its funds in Australian equities and 30% of its funds in corporate bonds. During this time period, you held a $100 million equally-weighted portfolio of the following four stocks, with the total return as the sum of capital gains and dividend yields during the 12-month period. You also held $20 million in corporate bonds, which generated a return of 7%, with a standard deviation of returns of 12%. The correlation of returns between your equity portfolio and your bond portfolio was 0.30. (a) (4 marks) Calculate the performance of your entire portfolio and the benchmark portfolio.
